__ 15 MT-300 Pico Broadcaster Operator Manual NOTE: When not streaming content to your MT300, turn off your transmitter by removing power to the device. 5. Streaming 5.1 Stream content to device If you are using a Bright Sign box youll need to refer to their manual. If you are using a PC you can use the VLC media player as an example. The application can be found here: http://www.videolan.org/vlc/index.html. If you are unfamiliar with VLC media player follow the instructions below. We are currently using VLC for streaming (www.videolan.org). This configuration has been tested using version 1.0.5 and 1.1.11. We suggest you download the latest version, its free. For more information go to www.meldtech.com/support Setting up the PC (IP address scheme assumes MT300 factory default settings) In a Command prompt window type IPCONFIG to view the PC IP address. Note: When using direct connection, make sure the PC and MT300 are in the same IP domain. Set the computers IP Address to a static address on the same subnet as the MT300 (e.g., 192.168.1.100) in a Command prompt window type ping 192.168.1.193 (This operation sets up an ARP entry on the PC) If properly working the ping command will return Request timed out message. This means the Ping command properly saw the MT300 but the MT300 did not respond back, which is to be expected as the MT300 is a one-way streamer and cannot reply. If it says not connected, check physical connection and power MT300. Make sure ARP table registry is correct In a Command prompt window type type Arp a __ 16 MT-300 Pico Broadcaster Operator Manual You should see the device Internet Address: 192.168.1.193 If using VLC GUI Streamer Configuration Set to RTP streaming mode Address:
